327 SeriesDirect Acting Solenoid Valves

Introducing the ASCO 327 Series

The ASCO 327 Series from Emerson is a universal, direct acting solenoid valve available in multiple variations of materials, power, flow and certification. Due to our flexible range and industry expertise, it is suitable for a wide variety of applications, such as actuator piloting, compressor unloading and utilities control, and also as part of a broader offering of engineered solutions that includes actuator control packages, redundant control systems and bypass panels.

With its unique design and strong safety accreditation, it is clear to see why the 327 Series is a proven safe, reliable and adaptable solution that can withstand even the most demanding environments in the process industry, with over one million valves installed in the industry to date.

Safe, Flexible and Reliable

Research has shown that a significant proportion of process plant failures and unplanned shutdowns are down to valve malfunction. So why not fit valves you know you can trust? The 327 Series’ robust design ensures reliable operation while the unique seal concept prevents valve sticking.

The 327 Series offers a wide range of benefits, including features that dramatically reduce your engineering time and commissioning costs. Our unique under pressure removable manual operator (MO) can be removed without isolating the valve or shutting down the instrument air system, and ensures a safe process without unnecessary downtime costs, and the low power consumption helps to reduce installation costs.

The provided SIL certification and PFD failure rate information helps to cut engineering time by simplifying the design process. The compact design and mounting holes of the 327 Series make the device easy to assemble to the actuator. It can also be incorporated into an actuator control system to make mounting and assembly even simpler. Add to this a wide choice of explosive environment protection and it soon becomes clear that the 327 Series is the ideal choice for a huge spectrum of applications which require excellent functional safety initiatives.
